- SPECIFICATION forming part of Letters Patent No. 364.0l-1, dated May 31x 1887.

(No model.)

.To all whom t may concern:

Be it known that I, HENRY S. HALE, of the city and county of Philadelphia, and Stat'e of Iennsylvania, have invented an Improvement 1n Car-Seats, of which the following is a specification.

My invention has reference to seats in general, but more particularly to what are known as car-seats and it consists in certain improvenients,v all of which is fully set forth in the following specification, and shown in the accompanying drawings, which form part thereof.

Heretofore seats of this characterhave been formed with reversible backs, and with seats so arranged that they may be tipped simulta' neously with the reversing of the back for the purpose of raising the forward edge of theseat, rendering it more comfortable. 'This pivotseat has been rocked or oscillated to assume the raised positions by means of a pivot-andlever connection actuated by a cam or pinion on the links of the back when in the act of throwing the back for reversing the seat. In

, addition to this it is also common to pivot the backs to the radial supporting arms or links therefor.

Prior to the date of this invention apatent was granted to me in whichl the seat was shifted by the striking ofthe seat-back upon the rear portion of the seat-cushion. The seat was tilted in the act of being shifted by being provided with two inclined or cam faces on the seat which run upon rollers on the seat-frame, and the power part of the cam or inclined faces were also provided withnotches, into which the rollers were received to lock the seat in its extreme positions. It has also been proposed to shift the seat by means of levers pivoted-to the seat-frame and to the back, and further connected to the seat by means of pins, between which the lower ends of the levers work. By moving the back the seat was shifted, and the work of moving the seat begun with raising the back. The seat was tilted by means of curved guides upon which it rested. It has also been proposed to pivot the seat and connect it on each side of the fulcrum with slides, which are supported at their free endv in a casting. These slides Were'reciprocated in opposite directions by cams secured to the these devices in this application.

I therefore do not claim any of Broadly speaking, the shifting and tilting seat operated by the seat-back is not new; but these features, when combined in the manner and with the improvements hereinafter specified,

the arms.

produce decidedly improved4 results, and a.

greater simplicity of construction is obtained. The object of my invention is to formacarseat in which the seat shall be capable of tip-` ping and moving toward the, raised edge or front, and in which the back, while being free and independent of said seat, shall nevertheless actuate said 'seat to cause it to assume the desired positions.

In carrying out my invention I provide the seat-frame with incline-d planes or cani-faces arranged in opposite directions, and upon which the seat-cushion support rests, and which when movedY over these inclines is caused to advance toward the front of the seat-frame, and at the same time be tipped so as to raise its forward edge, and consequently the seat or cushion which rests upon saidsupport is caused to take a corresponding movement. This support for the seat is connected to four vertically-sliding plates or rods arranged upon the arms of the seat-frame, which are adapted to receive the seat-back links and be thrust' down by the Weight of the said back, and it is by this vertical' movement that the seat-support is caused to more over the incline plane.v This construction may be used with a back rigidly secured to the links, or, what is more preferable, with a back hinged to the links, substantially as shown, and arranged to lock automatically after being thrown in position. (See dotted lines, Fig. 2.) f

Referring to the drawings, Figure l is a perspective View of a'car-seat embodying my invention,with aportion of the cushion and supporting-frame broken away. Fig. 2 is a crosssection of same on line y1). Fig. 3 isa crosssection through one of the arms and its close connections on line x a. tion of the arm, guide,land actuating-slide on line z z. Fig. -5 is a cross-section of the same through line w w, and Fig. 6 is a perspective. view of one of the seat support actuating slides and its guide.

levers ofthe back, by which itis connected to Fig. 4 is a cross-secis guided.

A is the fixed frame of the seat, and B is the arm thereof.

C is the back, which is preferably pivoted at D to the supporting links or arms D at d, which are hinged to the arm B.v The frame A is connected by bars G, received on each end by a socket, g, formed upon a casting, F,which is secured to the frame A. The upper parts .of these sockets are made with inclined surfaces or planes H.A

I are the end plates of the seat-cushion support, and are connected by the supportingrails J', upon which the seat-cushionlE rests. These end plates, I, are provided with projections ,which rest upon the inclined planes H, which planes on each end point in opposite directions. The distance between said projections I ou the end plate is equal to the distance between the lowest point in one incline plane and the highest point inthe other, where by when one side of the cushion -support is caused to rise the other side is vcaused to descend, and this action is induced by a lateral shifting of the said support over the incline planes. If desired, these projections z' may be provided with rollers or anti-friction wheels, though in practice they are not found necessary.

To prevent any possibility of the speatsup port rising, except in accordance with the inclinations of the inclined planes or cams H and stud or roller J upon the outer face of the plates I, it may work in slots K in the frameplates F, though in practice this is found to be unnecessary to the perfect working of the device; but its use would prevent accidental vertical displacement of the seatcushion support. To work the seat-cushion support over the incline'planes, whereby it obtains its oscillating as Well as reciprocating adjustment,

VI provide the following mechanism:

` Secured to the arm B is a casting or bracket, P, having a T- shaped head, (see Fig. 6,-) which acts as a support for the Vlinks D of the back C and receives the weight of the said back. Working upon these guides P are the vertically-moving slides M, the upper portion of which is provided with a T-slot, O, to fit upon the T- shaped guides P, and with an upward extenston, Q, to hold the link D of the back against lateral displacement; Thelower portion of said slide is provided with a rib, m, which works in acorrespouding groove, a, in the frame A, and to prevent excessive wear upon the wood-work of the s aid frame a slotted metallic guide, N, maybe let into the said frame, and upon which the slide M Works and These slides M are located in the same position as are now occupied by the locks in ordinary car-seats, and are Afour in number,

' and are connected at their bottoms by links L support, `and the seat-cushion will assume the position indicated in dotted lines.

By this construction it is seen that the seatback is entirely separate and distinct and independent of the seat-cushion or its actuating and support device, and yet its weight is utilized to positively actuate the seat proper to cause it to assume the position desired and then lock itin such position. This simplifies the construction and reduces the liability to get out of order, and the ends of the seat arms or frame are unobstructed, thereby admitting of the highest finish and ornamentation and overcoming the effect of a heavy and cumbersome piece of mechanism. A more improved result is obtained by hipging the back C to the links D; but the invention is equallyapplicable to a back which is rigidly secured to the links or arms D.

The details of construction may be greatly modified without in anywise departing from the spirit of the invention, and therefore,while I prefer the construction shown, Ido notlimit myself thereto.

Having now described my invenlion,what I claim as new, and desire to secure by Letters Patent, is

1. In a seat,the combination of a fixed frame provided with cam or inclined planes or faces with a seat proper supported thereon and adapted to be retained in a tipped position thereby and a slot and a centrally-located piu or roller connection on the ends to prevent said movable seat portion from being displaced and yet admit of its being freely tipped and shifted, substantially as and for the purpose specified.

2. In a seat, the combination of a fixed frame provided with cam or inclined faces of considerable width and sharply inclined with relation to the seat with a seat proper having end plates formed with extended projections i, which work upon the cam-faces, and recesses between said projections and front and back portions of the seat to receive the cam-faces and act as stops to limit the tilting of the seat proper, thewhole being formed to obtain a considerable degree of tilting with but asmall shifting movement, substautiall y as and for the purpose specified.

3. In a seat,the combination of a fixed frame provided with cam orinclined planes orfaces of considerable width with a seat proper having narrow projections which workupon said fixed cams, whereby the seat is supported thereon and adapted to assume a tipped position and free to change such position without creating excessive friction, a hinged seat-back, and vertically-moving slide mechanism, sub stantially as set forth, connecting with the movableseat portion and in like path of the seat-back or its links, whereby the weight of the seat-back shall reciprocate said seat portion, substantially as and for the purpose specified.
